+## Implementation Gap Analysis
+
+The failures fall into these categories, ordered by impact (tests unlocked):
+
+---
+
+### 1. `childNodes` list context — HIGH IMPACT
+
+**Affects**: t/04node.t (stops at test 7), t/16docnodes.t (stops at line 29),
+and any test that does `my @kids = $node->childNodes`.
+
+**Root cause**: `childNodes` always returns a single `XML::LibXML::NodeList`
+blessed arrayref, even in list context. Perl's `my @arr = $node->childNodes`
+puts the NodeList object itself into `@arr[0]` (scalar), not the individual nodes.
+
+**Expected behaviour**:
+- **List context**: returns a flat list of individual `XML::LibXML::*` node objects.
+- **Scalar context**: returns an `XML::LibXML::NodeList` blessed reference.
+
+**Fix**: In `XMLLibXML.java`, check `ctx == RuntimeContextType.LIST` and return
+individual wrapped nodes (similar to how `findnodes` already does this).
+
+```java
+public static RuntimeList childNodes(RuntimeArray args, int ctx) {
+ NodeList children = getNode(args.get(0)).getChildNodes();
+ if (ctx == RuntimeContextType.LIST) {
+ RuntimeList result = new RuntimeList();
+ for (int i = 0; i < children.getLength(); i++)
+ result.add(wrapNode(children.item(i)));
+ return result;
+ }
+ RuntimeArray arr = new RuntimeArray();
+ for (int i = 0; i < children.getLength(); i++)
+ RuntimeArray.push(arr, wrapNode(children.item(i)));
+ return ReferenceOperators.bless(arr.createReference(),
+ new RuntimeScalar("XML::LibXML::NodeList")).getList();
+}
+```
+
+Also add `getChildnodes` as an alias (used in t/16docnodes.t).
+
+---
+
+### 2. Missing `$XML::LibXML::skipXMLDeclaration` in `toString` — HIGH IMPACT
+
+**Affects**: t/02parse.t stops producing output after test 181 (all remaining
+tests require round-trip via `toString` with `$skipXMLDeclaration = 1`).
+
+**Root cause**: `documentToString` and `toString` (node serialization) ignore
+the `$XML::LibXML::skipXMLDeclaration` package variable.
+
+**Fix**: In `XMLLibXML.java::serializeNode`, read the Perl global:
+
+```java
+private static String serializeNode(Node node, boolean format, boolean withDecl) {
+ if (withDecl) {
+ RuntimeScalar skip = GlobalVariable.getGlobalVariable("XML::LibXML::skipXMLDeclaration");
+ if (skip != null && skip.getBoolean()) withDecl = false;
+ }
+ // ... existing Transformer code ...
+}
+```
+
+Also respect `$XML::LibXML::skipDTD` (suppress DOCTYPE in output) and
+`$XML::LibXML::setTagCompression` (self-closing vs empty element style).
+
+---
+
+### 3. `keep_blanks(0)` does not strip whitespace text nodes — HIGH IMPACT
+
+**Affects**: t/02parse.t `toString` round-trip tests (` ` → ``).
+
+**Root cause**: `setIgnoringElementContentWhitespace(true)` only strips
+*element content whitespace* (whitespace in element-only content models defined
+by DTD). For XML with no DTD, JAXP cannot classify content models, so the
+flag does nothing.
+
+**Fix**: After parsing with `keepBlanks=false`, walk the DOM tree and remove
+all `Text` nodes that contain only whitespace (i.e., `node.getNodeValue().trim().isEmpty()`).
+Implement this as a post-parse helper `stripBlankTextNodes(Document doc)`.
+
+---
+
+### 4. Missing Document methods — HIGH IMPACT
-API surface required (extracted from `XML/Diff.pm` and `t/1.t`):
+Each missing method stops a whole test file at the first call.
-| Class | Methods |
+| Missing method | Caller | Fix |
+|---|---|---|
+| `createDocument` | t/03doc.t line 140 | Creates new `Document`; calls `DocumentBuilder.newDocument()` then wraps |
+| `getDocumentElement` | t/08findnodes.t, t/20extras.t, t/29id.t | Alias for `documentElement` |
+| `getChildnodes` | t/16docnodes.t | Alias for `childNodes` on Document |
+| `getVersion` | t/14sax.t (via SAX/Parser.pm) | Alias for `version` / `documentVersion` |
+| `createExternalSubset` | t/07dtd.t | Creates external DTD reference; can return undef stub initially |
+| `toStringHTML` | various | Serialize as HTML (no XML declaration, HTML entities); can delegate to Jsoup or Transformer |
+
+`createDocument` signature: `XML::LibXML::Document->createDocument($version, $encoding)` —
+returns a new, empty Document node blessed as `XML::LibXML::Document`.
+
+---
+
+### 5. Missing Element methods — HIGH IMPACT
+
+| Missing method | Caller | Fix |
+|---|---|---|
+| `tagName` | t/06elements.t line 34 | Alias for `nodeName` (W3C DOM calls it `tagName` on Element) |
+| `lookupNamespaceURI($prefix)` | t/10ns.t line 48 | `Element.lookupNamespaceURI(prefix)` in JDK DOM |
+| `new($name)` | t/62overload.t line 10 | Constructor — creates a detached Element node |
+
+`XML::LibXML::Element->new($name)` should call `createElementNS` on a
+temporary document and return the wrapped node. This requires a shared
+scratch `Document` kept as a static field in `XMLLibXML.java`.
+
+---
+
+### 6. Missing `XML::LibXML::XPathExpression->new` — HIGH IMPACT
+
+**Affects**: t/09xpath.t, t/30xpathcontext.t (stop at first call).
+
+**Root cause**: No `new` method registered for the `XML::LibXML::XPathExpression` class.
+
+Upstream `XML::LibXML::XPathExpression->new($expr_string)` compiles an XPath
+expression for reuse. JDK has no compiled-XPath type separate from
+`XPathExpression` objects, but we can store the string and compile lazily.
+
+**Fix**: Register a `new` method in `XMLLibXML.java`:
+```java
+module.registerMethodInPackage("XML::LibXML::XPathExpression", "new", "xpathExprNew");
+module.registerMethodInPackage("XML::LibXML::XPathExpression", "expression", "xpathExprStr");
+```
+Store the expression string in the blessed hash.
+
+---
+
+### 7. Error message format mismatches — MEDIUM IMPACT
+
+**Affects**: t/02parse.t test 29/170 (`like($@, qr/^Empty String at/)`).
+
+**Root cause**: When `parse_string(undef)` is called, our implementation
+throws "Premature end of file" (JAXP's message for empty input). The test
+expects the error to start with `"Empty String at"`.
+
+**Fix**: In `_parse_string`, detect `undef` or zero-length input before
+calling JAXP, and throw with the expected prefix:
+```perl
+if (!defined $str || $str eq '') {
+ Carp::croak("Empty String");
+}
+```
+(This is already done in the Perl shim `XML/LibXML.pm` for the `parse_string`
+wrapper — double-check the code path for the case where `$str` is Perl `undef`
+vs empty string vs `"\n"`.)
+
+Also: `parse_file` error messages should start with `"$filename:$line: parser error : ..."`.
+Currently we emit `"XML::LibXML::parse_file: The markup in the document following..."`.
+Fix by catching `SAXParseException` and reformatting:
+```java
+throw new RuntimeException(filename + ":" + e.getLineNumber() +
+ ": parser error : " + e.getMessage());
+```
+
+---
+
+### 8. Missing Text methods — MEDIUM IMPACT
+
+**Affects**: t/05text.t (stops at test 4).
+
+| Missing method | Fix |
|---|---|
-| `XML::LibXML` (parser) | `new`, `keep_blanks`, `parse_string`, `parse_file` |
-| `XML::LibXML::Document` | `documentElement`, `setDocumentElement`, `createElement`, `toString` |
-| `XML::LibXML::Node` | `nodeName`, `nodeType`, `parentNode`, `nextSibling`, `previousSibling`, `childNodes`, `firstChild`, `attributes`, `cloneNode`, `appendChild`, `insertBefore`, `insertAfter`, `removeChild`, `unbindNode`, `hasChildNodes`, `textContent`, `toString`, `setData`, `setNamespace` |
-| `XML::LibXML::Element` | `getAttribute`, `setAttribute`, `removeAttribute`, `findnodes` |
-| `XML::LibXML::NodeList` | array deref, `size`, `pop`, `get_node` |
+| `substringData($offset, $count)` | `node.getNodeValue().substring(offset, offset+count)` |
+| `appendData($str)` | `node.setNodeValue(node.getNodeValue() + str)` |
+| `insertData($offset, $str)` | String insertion at offset |
+| `deleteData($offset, $count)` | String deletion |
+| `replaceData($offset, $count, $str)` | String replacement |
+| `splitText($offset)` | DOM `Text.splitText(offset)` |
-Total: ~30 user-visible methods.
+These are `CharacterData` DOM methods — all straightforward.
-**Estimated size**: ~400–700 lines of Perl shim (`XML/LibXML.pm`) +
-~600–1,000 lines of Java glue (`XMLLibXML.java`) ≈ **1,000–1,700 lines**.
-Most methods are one-line wrappers over `org.w3c.dom` calls.
+---
-**Effort**: 2–4 days.
+### 9. Missing Dtd support — MEDIUM IMPACT
-**Acceptance criteria**:
-1. `jcpan -t XML::Diff` reports `Result: PASS` (38/38 in `t/1.t`).
-2. `make` (full unit-test suite) still green.
-3. `make test-bundled-modules` still green.
-4. New unit tests under `src/test/resources/unit/xml_libxml/` covering the
- methods above (parse → manipulate → serialize round-trips).
+**Affects**: t/07dtd.t, t/13dtd.t.
-### Tier B — "Useful" coverage (~80% of CPAN consumers)
+| Missing | Fix |
+|---|---|
+| `XML::LibXML::Dtd->new($name, $url)` | Parse DTD from URL using `DocumentBuilder.parse` with DTD handler; stub can return an opaque object |
+| `XML::LibXML::Dtd->parse_string($str)` | Parse DTD from string; stub possible |
+| `$doc->createInternalSubset($name, $pid, $sid)` | Creates DOCTYPE declaration |
+| `$doc->createExternalSubset($name, $pid, $sid)` | Creates external DTD ref |
-Extends Tier A with:
+Full DTD introspection (entity/element/attribute declarations) is a Tier C feature.
+A stub that returns objects passing `isa('XML::LibXML::Dtd')` unblocks tests that
+only check `defined($dtd)`.
-- Full namespace handling (`createElementNS`, `getAttributeNS`, `setAttributeNS`, `XPathContext` with `registerNs`).
-- `find`, `findvalue`, `exists` (XPath returning string/boolean/list as appropriate).
-- `parse_html_string`, `parse_html_file` via Jsoup.
-- `Comment`, `PI`, `CDATASection`, `DocumentFragment` node types.
-- `addNewChild`, `addChild`, `getElementsByTagName[NS]`, `getNamespaces`.
-- Encoding/version on `Document`, `toFile`, `toStringHTML`.
-- Basic `XML::LibXML::Reader` (StAX-backed, optional).
-- Error objects with line/column where JAXP exposes them.
+---
-**Estimated size**: ~1,500–2,500 lines Perl + ~1,500–2,500 lines Java ≈
-**3,000–5,000 lines total**.
+### 10. `XML::LibXML::Common::encodeToUTF8` UTF-16 — MEDIUM IMPACT
-**Effort**: 1.5–3 weeks.
+**Affects**: t/42common.t tests 5–7 (UTF-16 string is expected to be 2× the byte length).
-Unblocks: XML::Atom, XML::Feed, SOAP::Lite (XML path), XML::Compile basics,
-XML::RSS::LibXML, XML::Twig::XPath, etc.
+**Root cause**: Our `encodeToUTF8` returns a UTF-8 encoded string (4 bytes per
+char for non-BMP), but the test expects the UTF-16 encoded version to have
+`2 × char_count` bytes.
-### Tier C — Comprehensive
+`XML::LibXML::Common::encodeToUTF8($charset, $str)` — converts $str
+(already internal Perl string) *from* $charset *to* UTF-8 bytes. When
+`$charset` is `"UTF-16"`, libxml2 just re-encodes; JDK should do the same.
+The fix is to call `str.getBytes(StandardCharsets.UTF_16)` (or the specific
+variant) and wrap the result, not re-encode as UTF-8.
+
+---
+
+### 11. `parse_html_file` — MEDIUM IMPACT
-Adds: DTD/RelaxNG/XSD validation, XInclude, full SAX adapter
-(`XML::LibXML::SAX`), `XML::LibXML::Pattern`, custom error handlers,
-DOCTYPE manipulation, `XML::LibXML::PrettyPrint`, schema introspection.
+**Affects**: t/12html.t (stops after test 1).
-**Estimated size**: ~7,000–11,000 lines total. Effort: 1.5–3 months.
+Our implementation has `parse_html_string` via Jsoup, but `parse_html_file`
+is missing. Fix: add a thin wrapper that reads the file and calls
+`parse_html_string`.
-Reference: upstream XML::LibXML 2.0210 ships ~10k lines of `.pm` plus
-~5k lines of `.xs` glue.
+---
+
+### 12. SAX callbacks / `match_callback` etc. — MEDIUM IMPACT
+
+**Affects**: t/17callbacks.t (stops at `match_callback`).
+
+The callback system (`match_callback`, `read_callback`, `open_callback`,
+`close_callback`) is used to intercept file loading during parse.
+These are Tier B features. Stub implementations that accept the
+argument and do nothing will let most tests proceed.
+
+---
+
+### 13. `toStringC14N` / Canonical XML — LOW IMPACT
+
+**Affects**: t/24c14n.t.
+
+Canonical XML (C14N) serialization is a complex feature with well-defined
+W3C semantics. JDK ships no built-in C14N transformer. Options:
+- Apache Santuario (additional JAR dependency)
+- Manual implementation (feasible for basic C14N but not exclusive-C14N)
+- Stub that throws "not implemented"
+
+---
+
+### 14. `XML::LibXML::RelaxNG` and `XML::LibXML::Schema` — LOW IMPACT
+
+**Affects**: t/25relaxng.t, t/26schema.t.
+
+JDK supports XML Schema validation via `javax.xml.validation`. RelaxNG
+requires a third-party library (Jing JAR). Both are Tier C.
+Stub `->new` that throws "not implemented" or `->validate` that returns 1
+will let unrelated tests in the same file proceed (none in these files).
+
+---
+
+### 15. `XML::LibXML::Reader` (pull reader) — LOW IMPACT
+
+**Affects**: t/40reader.t, t/40reader_mem_error.t.
+
+StAX-backed implementation. Complex; deferred to Tier C.
+
+---
+
+### 16. `XML::LibXML::RegExp` — LOW IMPACT
+
+**Affects**: t/45regex.t.
+
+Wraps libxml2's regexp (based on XML Schema regex). JDK `java.util.regex`
+with schema-compatible mode. Stub `->new` unblocks.
+
+---
+
+### 17. XInclude — LOW IMPACT
+
+**Affects**: t/41xinclude.t.
+
+JAXP `DocumentBuilder` can resolve XIncludes via `setXIncludeAware(true)`.
+Currently not wired up.
+
+---
+
+### 18. DTD entity expansion — LOW IMPACT
+
+**Affects**: t/44extent.t.
+
+`expand_entities(0)` keeps entity references as entity-reference nodes in the
+DOM. JAXP by default expands entities. To preserve entity refs, set
+`DocumentBuilderFactory.setExpandEntityReferences(false)` (or use SAX with
+`setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, false)` and the lexical
+handler). Serialisation of entity refs in JAXP produces XML output with
+`&name;` only if `setExpandEntityReferences(false)` is set.
+
+---
+
+### 19. `addChild` on Text/Node — LOW IMPACT
+
+**Affects**: t/23rawfunctions.t.
+
+`addChild` is an alias for `appendChild` in some contexts, or a specialized
+form that accepts raw node types. Register as alias.
+
+---
+
+### 20. `base_uri` parser option — LOW IMPACT
+
+**Affects**: t/43options.t (stops at test 80, after 30 subtests pass).
+
+Parser attribute getter/setter. Store in `ParserOptions` hash; pass to
+`DocumentBuilder` as `setDocumentURI` on parsed document.
+
+---
+
+## Phased Plan

+9. Add DTD stubs (`XML::LibXML::Dtd->new`)
+10. Fix `encodeToUTF8` for UTF-16 input
+11. Add `parse_html_file`
+12. Stub callback methods (`match_callback`, etc.)
+
+**Estimated effort**: 2–5 days.

+### Tier C — Comprehensive
+
+Adds: full C14N, RelaxNG/XSchema validation, XInclude, pull Reader,

+# XML::LibXML — XS Shim Refactor Plan
+
+## Summary
+
+Replace our hand-written `src/main/perl/lib/XML/LibXML.pm` (~789 lines,
+incomplete) with the original upstream `LibXML.pm` (2371 lines, complete
+pure-Perl layer), patched only to remove `XSLoader`. Java continues to provide
+the underlying DOM primitives — just registered under the XS function names that
+the original Perl file expects.
+
+**Expected outcome**: the ~2000 lines of pure-Perl convenience code in the
+original file (wrappers, OO infrastructure, `NamedNodeMap`, `Namespace`,
+`_SAXParser`, `Pattern`, `RegExp`, `XPathExpression`, `InputCallback`, …) are
+picked up for free, with no additional Java work for those parts.
+
+---
+
+## Why this is better than the current approach
+
+| | Current | XS-shim |
+|---|---|---|
+| Perl layer LOC | ~789 (incomplete) | 2371 (upstream, complete) |
+| Missing methods | Dozens (removeChildNodes, nonBlankChildNodes, lookupNamespacePrefix, setNodeName, isEqualNode, toStringC14N, …) | None — already in upstream Perl |
+| Maintenance | Must hand-port every new feature | Only the ~80 XS primitives need Java |
+| Test compatibility | Custom semantics diverge from tests | Tests written for this exact Perl file |
+
+---
+
+## Step 0 — Understand what the original LibXML.pm calls
+
+The upstream file calls two kinds of methods:
+
+1. **Pure-Perl methods** — defined in the same file, need nothing from us.
+2. **XS boundary methods** — called as `$self->_someMethod(...)` or as bare
+ function calls (registered by `XSLoader` in the normal XS flow).
+ Java must register these.
+
+### Complete list of XS boundary calls made by LibXML.pm
+
+Extracted from the upstream source (`LibXML.pm` method calls that are NOT
+defined as `sub` in that file, and that appear in `LibXML.xs`):

+
+The upstream `Namespace` package in `LibXML.pm` uses `$$self` (scalar-ref
+dereference) for `isSameNode`. Our Namespace objects are hash refs, not scalar
+refs. **Patch required** in the Perl file (see Step 1 below).
+
+---
+
+## Step 1 — Patch `LibXML.pm` for PerlOnJava
+
+Source: `~/.cpan/build/XML-LibXML-2.0210-99/LibXML.pm`
+Target: `src/main/perl/lib/XML/LibXML.pm`
+
+Copy the upstream file and apply **only** the following minimal patches:
+
+### Patch A — Remove XSLoader, set `$__loaded`
+
+In the `BEGIN` block, remove:
+```perl
+use XSLoader ();
+```
+and replace:
+```perl
+XSLoader::load( 'XML::LibXML', $VERSION );
+undef &AUTOLOAD;
+```
+with:
+```perl
+# PerlOnJava: XS methods registered by XMLLibXML.initialize() via Java
+$XML::LibXML::__loaded = 1;
+```
+
+### Patch B — Remove LIBXML_RUNTIME_VERSION version check
+
+Remove the block that calls `LIBXML_RUNTIME_VERSION()` and `LIBXML_VERSION`:
+```perl
+{
+ my ($runtime_version) = LIBXML_RUNTIME_VERSION() =~ /^(\d+)/;
+ if ( $runtime_version < LIBXML_VERSION ) {
+ warn "Warning: ...";
+ }
+}
+```
+(Java stubs for these functions return equal values so the check would be a
+no-op, but removing it is cleaner.)
+
+### Patch C — Guard thread-import path
+
+In the `import` sub, wrap the `:threads_shared` path so it silently skips
+rather than dying when thread support is unavailable:
+
+```perl
+ if (grep /^:threads_shared$/, @_) {
+- require threads;
++ eval { require threads };
+ if (!defined($__threads_shared)) {
+- if (INIT_THREAD_SUPPORT()) {
++ if (eval { INIT_THREAD_SUPPORT() }) {
+```
+
+### Patch D — Fix `XML::LibXML::Namespace::isSameNode`
+
+The upstream uses `$$self == $$ref` (scalar-ref address comparison).
+PerlOnJava's Namespace objects are blessed hash refs, not scalar refs.
+
+Replace:
+```perl
+sub isSameNode {
+ my ( $self, $ref ) = @_;
+ if ( $$self == $$ref ){
+ return 1;
+ }
+ return 0;
+}
+```
+with:
+```perl
+sub isSameNode {
+ my ( $self, $ref ) = @_;
+ return (ref($ref) && $self == $ref) ? 1 : 0;
+}
+```
+
+### Patch E — `XML::LibXML::Namespace` field names
+
+The upstream XS stores Namespace objects as scalar refs to C structs.
+Our Java implementation (`makeNamespaceObject`) stores them as hash refs
+with keys `{prefix}` and `{uri}`.
+
+The upstream Perl package calls XS methods `localname`, `declaredURI`,
+`declaredPrefix`, `unique_key` on the C struct. Since our objects are hashes,
+add a pure-Perl fallback implementation of those XS methods inside the
+`XML::LibXML::Namespace` package:
+
+```perl
+sub localname { $_[0]->{prefix} }
+sub getLocalName { $_[0]->{prefix} }
+sub declaredPrefix { $_[0]->{prefix} }
+sub declaredURI { $_[0]->{uri} }
+sub getData { $_[0]->{uri} }
+sub getValue { $_[0]->{uri} }
+sub value { $_[0]->{uri} }
+sub nodeValue { $_[0]->{uri} }
+sub getNamespaceURI { 'http://www.w3.org/2000/xmlns/' }
+sub getPrefix { 'xmlns' }
+sub prefix { 'xmlns' }
+sub nodeType { 18 } # XML_NAMESPACE_DECL
+sub unique_key { ($_[0]->{prefix}//'') . "\n" . ($_[0]->{uri}//'') }
+```
+
+These replace the XS calls; the `nodeName` sub already in `LibXML.pm` will
+call `$self->localname` and pick up the pure-Perl version.
+
+---
+
+## Step 2 — New Java methods in `XMLLibXML.java`
+
+### 2a. `isBlankNode` helper (private static)
+
+```java
+private static boolean isBlankNode(Node node) {
+ short t = node.getNodeType();
+ if (t == Node.TEXT_NODE || t == Node.CDATA_SECTION_NODE) {
+ String v = node.getNodeValue();
+ return v == null || v.trim().isEmpty();
+ }
+ return false;
+}
+```
+
+### 2b. `childNodesFiltered(self, only_nonblank)`
+
+```java
+public static RuntimeList childNodesFiltered(RuntimeArray args, int ctx) {
+ Node node = getNode(args.get(0));
+ boolean onlyNonBlank = args.size() > 1 && args.get(1).getBoolean();
+ NodeList children = node.getChildNodes();
+ RuntimeList result = new RuntimeList();
+ for (int i = 0; i < children.getLength(); i++) {
+ Node child = children.item(i);
+ if (onlyNonBlank && isBlankNode(child)) continue;
+ result.add(wrapNode(child));
+ }
+ return result;
+}
+```
+
+### 2c. `removeChildNodes`
+
+```java
+public static RuntimeList removeChildNodes(RuntimeArray args, int ctx) {
+ Node node = getNode(args.get(0));
+ while (node.getFirstChild() != null)
+ node.removeChild(node.getFirstChild());
+ return scalarUndef.getList();
+}
+```
+
+### 2d. `lookupNamespacePrefix(self, uri)`
+
+```java
+public static RuntimeList lookupNamespacePrefix(RuntimeArray args, int ctx) {
+ Node node = getNode(args.get(0));
+ String uri = args.get(1).toString();
+ Node cur = node;
+ while (cur != null && cur.getNodeType() == Node.ELEMENT_NODE) {
+ NamedNodeMap attrs = cur.getAttributes();
+ for (int i = 0; i < attrs.getLength(); i++) {
+ Attr a = (Attr) attrs.item(i);
+ String n = a.getName();
+ if (a.getValue().equals(uri)) {
+ if (n.startsWith("xmlns:")) return new RuntimeScalar(n.substring(6)).getList();
+ if (n.equals("xmlns")) return new RuntimeScalar("").getList();
+ }
+ }
+ cur = cur.getParentNode();
+ }
+ return scalarUndef.getList();
+}
+```
+
+### 2e. `firstNonBlankChild`, `nextNonBlankSibling`, `previousNonBlankSibling`
+
+```java
+public static RuntimeList firstNonBlankChild(RuntimeArray args, int ctx) {
+ Node n = getNode(args.get(0)).getFirstChild();
+ while (n != null && isBlankNode(n)) n = n.getNextSibling();
+ return (n != null ? wrapNode(n) : scalarUndef).getList();
+}
+
+public static RuntimeList nextNonBlankSibling(RuntimeArray args, int ctx) {
+ Node n = getNode(args.get(0)).getNextSibling();
+ while (n != null && isBlankNode(n)) n = n.getNextSibling();
+ return (n != null ? wrapNode(n) : scalarUndef).getList();
+}
+
+public static RuntimeList previousNonBlankSibling(RuntimeArray args, int ctx) {
+ Node n = getNode(args.get(0)).getPreviousSibling();
+ while (n != null && isBlankNode(n)) n = n.getPreviousSibling();
+ return (n != null ? wrapNode(n) : scalarUndef).getList();
+}
+```
+
+### 2f. `setNodeName(self, newName)`
+
+```java
+public static RuntimeList setNodeName(RuntimeArray args, int ctx) {
+ Node node = getNode(args.get(0));
+ String newName = args.get(1).toString();
+ try {
+ if (node.getOwnerDocument() != null)
+ node.getOwnerDocument().renameNode(node, node.getNamespaceURI(), newName);
+ } catch (Exception ignored) {}
+ return scalarUndef.getList();
+}
+```
+
+### 2g. `nodeIsEqual(self, other)` — for `_isEqual` / `isEqualNode`
+
+```java
+public static RuntimeList nodeIsEqual(RuntimeArray args, int ctx) {
+ Node a = getNode(args.get(0));
+ Node b = getNode(args.get(1));
+ return new RuntimeScalar(a != null && a.isEqualNode(b) ? 1 : 0).getList();
+}
+```
+
+### 2h. `getNamespaceDeclURI(self, prefix)`
+
+```java
+public static RuntimeList getNamespaceDeclURI(RuntimeArray args, int ctx) {
+ Node node = getNode(args.get(0));
+ RuntimeScalar prefixArg = args.size() > 1 ? args.get(1) : null;
+ String prefix = (prefixArg == null || prefixArg.type == RuntimeScalarType.UNDEF)
+ ? "" : prefixArg.toString();
+ if (!(node instanceof Element)) return scalarUndef.getList();
+ String attrName = prefix.isEmpty() ? "xmlns" : "xmlns:" + prefix;
+ String val = ((Element) node).getAttribute(attrName);
+ return (val != null && !val.isEmpty()) ? new RuntimeScalar(val).getList()
+ : scalarUndef.getList();
+}
+```
+
+### 2i. `setNamespaceDeclURI(self, prefix, newURI)`
+
+```java
+public static RuntimeList setNamespaceDeclURI(RuntimeArray args, int ctx) {
+ Node node = getNode(args.get(0));
+ String prefix = args.get(1).toString();
+ RuntimeScalar newURI = args.size() > 2 ? args.get(2) : null;
+ if (!(node instanceof Element)) return scalarUndef.getList();
+ Element el = (Element) node;
+ String attrName = prefix.isEmpty() ? "xmlns" : "xmlns:" + prefix;
+ if (newURI == null || newURI.type == RuntimeScalarType.UNDEF)
+ el.removeAttribute(attrName);
+ else
+ el.setAttribute(attrName, newURI.toString());
+ return scalarUndef.getList();
+}
+```
+
+### 2j. `createEntityReference(self, name)`
+
+```java
+public static RuntimeList createEntityReference(RuntimeArray args, int ctx) {
+ Document doc = (Document) getNode(args.get(0));
+ return wrapNode(doc.createEntityReference(args.get(1).toString())).getList();
+}
+```
+
+### 2k. `namespaceIsEqual(self, other)` — for `XML::LibXML::Namespace._isEqual`
+
+```java
+public static RuntimeList namespaceIsEqual(RuntimeArray args, int ctx) {
+ try {
+ RuntimeHash h1 = args.get(0).hashDerefRaw();
+ RuntimeHash h2 = args.get(1).hashDerefRaw();
+ boolean eq = h1.get("prefix").toString().equals(h2.get("prefix").toString())
+ && h1.get("uri").toString().equals(h2.get("uri").toString());
+ return new RuntimeScalar(eq ? 1 : 0).getList();
+ } catch (Exception e) {
+ return new RuntimeScalar(0).getList();
+ }
+}
+```
+
+### 2l. Stubs for unused but called XS functions
+
+Add a single `nopMethod` stub and alias it to anything that just needs to
+return undef/empty without crashing:
+
+```java
+public static RuntimeList nopMethod(RuntimeArray args, int ctx) {
+ return scalarUndef.getList();
+}
+```
+Register as: `_end_sax_push`, `_processXIncludes`, `load_catalog`,
+`_default_catalog`, `_externalEntityLoader`, `_parse_sax_string`,
+`_parse_sax_fh`, `_parse_sax_file`, `_parse_sax_xml_chunk`,
+`_toStringC14N` (on Node), `attrSerializeContent`.
+
+---
+
+## Step 3 — Update `initialize()` registrations in `XMLLibXML.java`
+
+### 3a. Parser-level additions (on `XML::LibXML`)
+
+```java
+module.registerMethod("_parse_html_fh", null); // (implement or stub)
+module.registerMethod("_parse_html_file", null); // (implement or stub)
+module.registerMethod("_end_sax_push", "nopMethod");
+module.registerMethod("_processXIncludes", "nopMethod");
+module.registerMethod("load_catalog", "nopMethod");
+module.registerMethod("_default_catalog", "nopMethod");
+module.registerMethod("_externalEntityLoader", "nopMethod");
+module.registerMethod("_parse_sax_string", "nopMethod");
+module.registerMethod("_parse_sax_fh", "nopMethod");
+module.registerMethod("_parse_sax_file", "nopMethod");
+module.registerMethod("_parse_sax_xml_chunk", "nopMethod");
+```
+
+### 3b. Node-level additions (append to `nodeMethods` array)
+
+```java
+{"_childNodes", "childNodesFiltered"},
+{"_attributes", "attributes"},
+{"_toString", "toString"},
+{"_isEqual", "nodeIsEqual"},
+{"_toStringC14N", "nopMethod"},
+{"removeChildNodes"},
+{"lookupNamespacePrefix"},
+{"firstNonBlankChild"},
+{"nextNonBlankSibling"},
+{"previousNonBlankSibling"},
+{"setNodeName"},
+{"_getNamespaceDeclURI", "getNamespaceDeclURI"},
+{"setNamespaceDeclURI"},
+{"createEntityReference"}, // NOTE: belongs on Document, but harmless on Node too
+```
+
+### 3c. Document-level additions (append to `docMethods` array)
+
+```java
+{"_setDocumentElement", "setDocumentElement"},
+{"_toString", "documentToString"},
+{"createEntityReference"},
+```
+
+### 3d. Element-level additions (append to `elemMethods` array)
+
+```java
+{"_getAttribute", "getAttribute"},
+{"_getAttributeNS", "getAttributeNS"},
+{"_setAttribute", "setAttribute"},
+{"_setAttributeNS", "setAttributeNS"},
+{"_setNamespace", "setNamespace"},
+{"_getNamespaceDeclURI", "getNamespaceDeclURI"},
+{"setNamespaceDeclURI"},
+{"lookupNamespacePrefix"},
+{"setNodeName"},
+```
+
+### 3e. Attr additions
+
+```java
+module.registerMethodInPackage("XML::LibXML::Attr", "_setData", "setAttrValue");
+module.registerMethodInPackage("XML::LibXML::Attr", "serializeContent", "nopMethod");
+```
+
+### 3f. PI additions
+
+```java
+module.registerMethodInPackage("XML::LibXML::PI", "_setData", "piSetData");
+```
+
+### 3g. Namespace additions
+
+```java
+module.registerMethodInPackage("XML::LibXML::Namespace", "_isEqual", "namespaceIsEqual");
+```
+
+---
+
+## Step 4 — Remove our custom XML/LibXML.pm sections now covered upstream
+
+After switching to the upstream file, these packages from our old
+`XML/LibXML.pm` are **no longer needed** (upstream defines them):
+
+- `XML::LibXML::Namespace` — upstream defines it (with our Patch E additions)
+- `XML::LibXML::NamedNodeMap` — upstream defines it (pure Perl, complete)
+- `XML::LibXML::Node` base stubs — upstream defines them
+- `XML::LibXML::Document` Perl wrappers — upstream defines them
+- `XML::LibXML::Element` Perl wrappers — upstream defines them
+
+Anything in our old file that is NOT in the upstream file should be
+reviewed; most will be redundant or superseded.
+
+---
+
+## Step 5 — Handle `XML::LibXML::SAX.pm`
+
+The upstream `lib/XML/LibXML/SAX.pm` is a full SAX driver. Our current
+`src/main/perl/lib/XML/LibXML/SAX.pm` is a custom rewrite.
+
+Keep our custom `SAX.pm` for now. The upstream one calls many more XS
+functions we haven't mapped yet. Revisit in a later phase.
+
+---
+
+## Step 6 — Build and test
+
+```bash
+cd /path/to/PerlOnJava2
+make 2>&1 | tail -5 # must be BUILD SUCCESSFUL
+
+# Run the key test files
+cd ~/.cpan/build/XML-LibXML-2.0210-99
+/path/to/jperl t/04node.t 2>&1 | grep -c "^ok" # was 93, target ~195
+/path/to/jperl t/06elements.t 2>&1 | grep -c "^ok" # was 45
+/path/to/jperl t/10ns.t 2>&1 | grep -c "^ok" # was 11
+
+# Full suite via perl_test_runner (or jcpan -t):
+perl dev/tools/perl_test_runner.pl ~/.cpan/build/XML-LibXML-2.0210-99/t/ \
+ > /tmp/libxml_results.txt 2>&1
+grep "passed/total" /tmp/libxml_results.txt | tail -3
+```
+
+Target after this refactor: **≥ 70% pass rate** (up from 53.7%).
+
+---
+
+## Risks and mitigations
+
+| Risk | Mitigation |
+|---|---|
+| Upstream `$$self` scalar-ref idiom in `Namespace::isSameNode` | Patch D covers it |
+| `_childNodes` scalar context returns count (upstream XS behaviour) | The upstream Perl wrappers always call it in list context — no action needed |
+| `AttributeHash` tie in `XML::LibXML::Element` calls `__destroy_tiecache` / `DESTROY` | These use `Scalar::Util::weaken`; test and stub if needed |
+| `_toStringC14N` stub returns undef | Tests for C14N will still fail; acceptable for now |
+| Some upstream `BEGIN` code calls XS functions before `initialize()` runs | The `BEGIN` block only calls `LIBXML_RUNTIME_VERSION()` (removed by Patch B) and sets `$__loaded` |
+| `XML::LibXML::InputCallback` uses `lib_init_callbacks` / `lib_cleanup_callbacks` | These are registered on `XML::LibXML` already via our existing registrations (check and add if missing) |
+
+---
+
+## Files to change
+
+| File | Change |
+|---|---|
+| `src/main/perl/lib/XML/LibXML.pm` | Replace with patched upstream (2371 lines) |
+| `src/main/java/…/XMLLibXML.java` | Add ~15 new methods + registration aliases |
+| `src/main/perl/lib/XML/LibXML/SAX.pm` | Keep as-is (our custom version) |
+
+Do NOT change any test files.
+

+ PerlOnJava distroprefs for XML::LibXML.
+ XML::LibXML's Makefile.PL requires Alien::Libxml2 (pkg-config or share dir).
+ Neither is available under the JVM. Even if Alien::Libxml2 were satisfied,
+ LibXML.xs cannot be compiled or loaded (JVM cannot dlopen native .so/.dylib).
+
+ PerlOnJava bundles a Java-backed XML::LibXML implementation in the JAR
+ (src/main/perl/lib/XML/LibXML.pm + XMLLibXML.java). The backend uses
+ JDK standard APIs: javax.xml.parsers.DocumentBuilder, org.w3c.dom.*,
+ javax.xml.xpath.*, javax.xml.transform.*.
+
+ No commandline overrides are needed: Distribution.pm detects the Makefile.PL
+ failure and automatically generates a cross-platform fallback Makefile. The
+ fallback Makefile runs 'make test' with jperl and 'make install' skipping
+ files that are bundled in the JAR.

+ PerlOnJava distroprefs for XML::LibXML.
+ XML::LibXML's Makefile.PL requires Alien::Libxml2 which expects either a
+ system libxml2 (via pkg-config) or a share-installed build. Neither is
+ available under the JVM. Even if Alien::Libxml2 were satisfied, the
+ LibXML.xs XS file cannot be compiled (JVM cannot dlopen native .so/.dylib).
+
+ PerlOnJava bundles a Java-backed XML::LibXML implementation in the JAR
+ (src/main/perl/lib/XML/LibXML.pm + XMLLibXML.java). The backend uses
+ JDK standard APIs: javax.xml.parsers.DocumentBuilder, org.w3c.dom.*,
+ javax.xml.xpath.*, javax.xml.transform.*.
+
+ Tier A (required for XML::Diff) is fully implemented.
+ Skip configure, build, and install; our bundled copy is authoritative.

+=head1 NAME
+
+XML::LibXML::AttributeHash - tie an XML::LibXML::Element to a hash to access its attributes
+
+=head1 SYNOPSIS
+
+ tie my %hash, 'XML::LibXML::AttributeHash', $element;
+ $hash{'href'} = 'http://example.com/';
+ print $element->getAttribute('href') . "\n";
+
+=head1 DESCRIPTION
+
+This class allows an element's attributes to be accessed as if they were a
+plain old Perl hash. Attribute names become hash keys. Namespaced attributes
+are keyed using Clark notation.
+
+ my $XLINK = 'http://www.w3.org/1999/xlink';
+ tie my %hash, 'XML::LibXML::AttributeHash', $element;
+ $hash{"{$XLINK}href"} = 'http://localhost/';
+ print $element->getAttributeNS($XLINK, 'href') . "\n";
+
+There is rarely any need to use XML::LibXML::AttributeHash directly. In
+general, it is possible to take advantage of XML::LibXML::Element's
+overloading. The example in the SYNOPSIS could have been written:
+
+ $element->{'href'} = 'http://example.com/';
+ print $element->getAttribute('href') . "\n";
+
+The tie interface allows the passing of additional arguments to
+XML::LibXML::AttributeHash:
+
+ tie my %hash, 'XML::LibXML::AttributeHash', $element, %args;
+
+Currently only one argument is supported, the boolean "weaken" which (if
+true) indicates that the tied object's reference to the element should be
+a weak reference. This is used by XML::LibXML::Element's overloading. The
+"weaken" argument is ignored if you don't have a working Scalar::Util::weaken.

+=head1 NAME

+XML::LibXML::Literal - Simple string values.
+
+=head1 DESCRIPTION
+
+In XPath terms a Literal is what we know as a string.
+
+=head1 API
+
+=head2 new($string)
+
+Create a new Literal object with the value in $string. Note that " and
+' will be converted to " and ' respectively. That is not part of the XPath
+specification, but I consider it useful. Note though that you have to go
+to extraordinary lengths in an XML template file (be it XSLT or whatever) to
+make use of this:
+
+
+
+Which produces a Literal of:
+
+ I'm feeling "sad"
+
+=head2 value()
+
+Also overloaded as stringification, simply returns the literal string value.
+
+=head2 cmp($literal)
+
+Returns the equivalent of perl's cmp operator against the given $literal.

+=head1 NAME
+
+XML::LibXML::NodeList - a list of XML document nodes
+
+=head1 DESCRIPTION
+
+An XML::LibXML::NodeList object contains an ordered list of nodes, as
+detailed by the W3C DOM documentation of Node Lists.
+
+=head1 SYNOPSIS
+
+ my $results = $dom->findnodes('//somepath');
+ foreach my $context ($results->get_nodelist) {
+ my $newresults = $context->findnodes('./other/element');
+ ...
+ }
+
+=head1 API
+
+=head2 new(@nodes)
+
+You will almost never have to create a new NodeList object, as it is all
+done for you by XPath.
+
+=head2 get_nodelist()
+
+Returns a list of nodes, the contents of the node list, as a perl list.
+
+=head2 string_value()
+
+Returns the string-value of the first node in the list.
+See the XPath specification for what "string-value" means.
+
+=head2 to_literal()
+
+Returns the concatenation of all the string-values of all
+the nodes in the list.
+
+=head2 to_literal_delimited($separator)
+
+Returns the concatenation of all the string-values of all
+the nodes in the list, delimited by the specified separator.
+
+=head2 to_literal_list()
+
+Returns all the string-values of all the nodes in the list as
+a perl list.
+
+=head2 get_node($pos)
+
+Returns the node at $pos. The node position in XPath is based at 1, not 0.
+
+=head2 size()
+
+Returns the number of nodes in the NodeList.
+
+=head2 pop()
+
+Equivalent to perl's pop function.
+
+=head2 push(@nodes)
+
+Equivalent to perl's push function.
+
+=head2 append($nodelist)
+
+Given a nodelist, appends the list of nodes in $nodelist to the end of the
+current list.
+
+=head2 shift()
+
+Equivalent to perl's shift function.
+
+=head2 unshift(@nodes)
+
+Equivalent to perl's unshift function.
+
+=head2 prepend($nodelist)
+
+Given a nodelist, prepends the list of nodes in $nodelist to the front of
+the current list.
+
+=head2 map($coderef)
+
+Equivalent to perl's map function.
+
+=head2 grep($coderef)
+
+Equivalent to perl's grep function.
+
+=head2 sort($coderef)
+
+Equivalent to perl's sort function.
+
+Caveat: Perl's magic C<$a> and C<$b> variables are not available in
+C<$coderef>. Instead the two terms are passed to the coderef as arguments.
+
+=head2 reverse()
+
+Equivalent to perl's reverse function.
+
+=head2 foreach($coderef)
+
+Inspired by perl's foreach loop. Executes the coderef on each item in
+the list. Similar to C
